z emma. (ci. 141-1) This invention relates generally to flushing andcleaning devices, and particularly to a flusher for automobile radiators.

The main object of 'this invention is to construct a highly eillcient form of radiator flusher by means of which all of the foreign substances lodged in the radiator cores will be removed The -third object is to construct a device of the class described which will be useful for flushing radiators and motor blocks with a continuous circulation of cleaning solution and compressed air by what we refer to as a reverse ush method.

These and other objects are accomplished in the manner set forth-in the following specification as illustrated in the accompanying drawings, in which: 1

Similar numerals refer to vsimilar parts throughout the several views.

Referring in .detail .to thev drawings. there is shown a casing Il which is divided by 'a partition i2 into an upper compartmentm and a lower compartment I4. The casing il is mountf 'ed on the castors I5 for convenience in moving same about.

, In the top l5 is formed an opening i1 around which is disposed a glass cylinder -I3 which contains the screen pocket I3. A hinged cover is placed over the cylinder I3 and the screen i3. The cover 20 contains an air vent opening 2| and an inlet nipple 22 to which is connected a hose 23 which isconnected to the top side 24 of an automobile radiator 25 whose lower side 23 is connected by a hose 21 to the pipe 25 whose.. downturned end 29 is provided with a check valve 3 3 which closes automatically against the flow of liquid therethrough in a downward direction.

'Ihe lower end 3i' of the downturned pipe 29 is open and has `projecting thereinto a U-shaped pipe 32 as shown in Fig. 5.

In the partition I2 is formed an opening 33 which is closable by a valve 34 which is mounted on the lower end of the rod 35 which projects upwardly through the .top I6. p

A float 36 is mounted'on the arm 31 which is hinged in the pivot 33 to the casing Il. To the float arm 31 is attached the plunger 39 on whose upper end is adjustably secured the block 40 by means of the set screw 4I. The Iblock 40 has projecting therefrom the lugs 42 and 43, the purpose of which will be explained later. The plunger 33 extends through the top I6 and guides therein.

Referring to the control valve itself, same will be seen to consist of an elongated shell 44 which isv divided by the partition 45 into the upper cylinder 46 and .the lower cylinder 41. In the upper cylinder 46 is disposed the piston 43 through which extends the transverse port 49 which for convenience is shown in straight lines in Figa-3,

Y 4 and 6 which registers with the ports 50 yandf5| m the sneu u while the piston as is in its lowermost position, and which registers with the ports '52 and 53 while the piston 48 is in its uppermost position, which is determined by the central stop 54 which engages the head 55 as shown in Fig. 4:;

whereas the downward position of the piston 43 n iscontrolled by the nuts 56 on the rods 51 which project upwardly from the piston 48 and slidably through the head 55. The head 55 is provided with a vent opening 53. Springs 51-A urge the piston 43 downwardly.

VAlong one side of the shell 44 is formed a passageway 53 which communicates with the ports 5l and 53. The port 52 opens to the atmosphere. j I l The port 59 communicates with the chamber 99 whe lowermost end 9| is oi' a reduced diameter and is normally closed by the ball check 92 which is urged toward a closed position by means of a spring I9 which is held in compression by means of the screw'plug 94.

Rotatably mounted in the enlarged portion 95 -of the shell 44 is a valve 69 having the central y the lower end of the cylinder 46.

A by-pass channel 14 has its port 15 connecting with the cylinder 41 and its port 18 connecting with the cylinder 46. The piston 49 is provided with a horizontal port 11 which communicates with the port 16 when the piston 48 is in its lowermost position. The port 11 has an upturned portion 18 which opens through the top of the piston 48. The lowermost piston 1 9 is slidable within the lowermost cylinder 41.

Attached to the piston 19 is the rod 95 around which is placed the spring 88 which urges the piston 19 upwardly. Connected to the lower end of the passageway 59 is an air pipe 8| which communicates with the compartment I4. 'I'he pipe 9| includes the safety valve 82 which may be of any desired type.

A pressure gage 89 is connected to the Passageway 59 by means of a pipe 84. Air from a source of supply not shown is admitted through a pipe 85 under the con-trol of a manually operated valve 86 to t'he opening 1-I to the radial opening 19 and thence through the central opening 91 from whence i-t can gain admission to the underside of the piston 48.

It is desirable to provide a pair of stops 91 and 88 to limit the movements of the valve 99 which is provided with an operating lever 89 which is secured to the valve 99 and rocks between the stops 81 and 88. The end 9| of lthe lever 89 is disposed between the lugs 42 and 49 oi' the block 40.

The operation of the device is as follows:

Assuming that it is desired to clean the radiator 2'5 which is installed in an automobile or removed therefrom as the case may be, it is Ilrst necessary to attach .the radiator 25 by means of the hose lines 29 and 21 to the device, as diown in Fig. 1. A quantity of cleaning uid 9| with alkaline or acid solvents, as the case may require, is now placed within the compartment I9 through the lllter I9. It will be borne in mind that up to this point there is no air under pressure above that of the atmosphere within the system and that the spring 89 is urging the piston 19 upwardly causing the valve 94 to close thereby confining the liquid within the compartmen't I9. When the predetermined level is reached, the lug 42 through the iloat 99 moves the lever arm 89 upwardly permitting air from the pressure pipe 85 to liow in 'two directions, first through the opening 9| and the ports Il, 49 and 5| into .the passageway 59 and also through the openings 1-I and 91and 19 into the cylinder 48 below the piston 49 causing the piston 49 to rise and move the port `49 out of register with the ports 59 and 5I thereby cutting of! the now ot air to the passageway 59. The

piston 49 continues to travel upwardly until the 'piston 19 which is within the lower cylinder 41 causing it to move downwardly and open the valve 94. The liquid 9| within the compartment I9 now nows by gravity through the opening 99 into the compartment I4 filling same.

As the liquid 9| leaves the compartment I9, the float 98 falls causing the position oi' the valve 99 to be reversed to the position shown in Fig. 8 thereby cutting on the supply of air from the pipe '95. Air is now permitted to exhaust imm the underside o! the piston 49 to the atmospherethrough the opening 99 as shown in Figs. 6 and 8. The piston 48 now descends slowly ilrst covering the port 19 which prevents the exhausting of the air from the top side of the piston 19 holding the valve 94 open and insuring the complete drainage of the liquid 9| to the lower compartment I4. When the piston 48 has descended suiiiciently far to cause the port 49 to register with the ports 50 and 5I and the ports 11 and 18 to register with each other, then air escapes from the top side of the piston 19 to the port 15 and 'oy-pass 14 and port 19 to the top side of the piston 48 from whence it escapes through the vent 58 to the atmosphere.

Since the ports 49, 59 and 5I are in register, air can now pass into the passageway 59 and through the pipe 9| into the compartment I4 forcing the material from the lower compartment I'4 upwardly through the pipe 29 and hose 21 through the radiator 25, the excess liquid 9| passing upwardly through the hose 29 through the illter I9 into the compartment I9. As the `level of the liquid 9| in the compartment I4 lowers below the upper end of the pipe 92, lt causes air to mix with the liquid passing upwardly through the pipe 29 causing a bubbling action of the water within the radiator 25 which tends to loosen the particles which are lodged therein.

As the water continues to fall until its level is below the end 9| of the pipe 29, a larger proportion of air passes through the radiator 2l causing a more violent action dislodging more of the foreign matter and carrying It over into the illter I9 from whence it is subsequently removed. By the time a sumclent amount of liquid 9| has been returned to the compartment I9, the iloat 99 has again risen and carried the block 49 to the-position shown in Fig. I restoring the parts to the commencement oi' the cycle of operation.

It can be seen that by this apparatus, a radiator may be automatically cleaned in a most thorough mannerand all the sediment therein removed therefrom, action being intermittent and suiiiciently violent to remove any form of incrustation or deposit without injury to the radiator itself.

It will be observed that the device consists of three essential parts, namely, the lowermost compartment |4 which is an aerating compartment from which the liquid is delivered to the Y radiator, a storage compartment I9 in which the cleaning liquid is held at intermittent periods of j the storage compartment.

While we have referred to this device as being a radiator cleaner for automobiles, i-t is evident that it will be just as useful for cleaning radiators for stationary motors and for coils of various kinds and also for engine blocks themselves.

We are aware that numerous forms of radiator cleaners have been constructed in the past and i-t is therefore not our intention tov cover such devices broadly, but we do intend to cover all such forms and modiiications thereof as fall lfairly within the appended claims.
